Sand mastic in East Lavant
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on tenement windows, period & listed homes and stone surrounds, and people most often call us about open joints round the window box and mastic that needs renewing before redecorating.
Homes in small places like East Lavant often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Keep modern sealant off the mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Frames and glazing around East Lavant
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Goodwood House (about 1.5 miles east) nearby, there’s older building stock in the area around East Lavant as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Lavant CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Different surfaces, different methods
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Why deal with it now?
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In a small place like East Lavant, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
